LOUIS SOCI-IUREK, OF MILWAUKEE, WISCONSIN- FILTER-PULP WASHER.

Specification of Letters Patent.

Patented Jan. 11, 1916.

Application filed September 2, 1909. Serial No. 515,935.

To all whom it may concern:

Be it known that I, LOUIS SooHURnK, a citizen of the United States, andresident of Milwaukee, in the county of Milwaukee and State oflVisconsin, have invented certain new and useful Improvements in Filter-Pulp Vashers; and I do hereby declare that the following is a full,clear, and exact description thereof.

My invention consists in what is herein particularly set forth withreference to the accompanying drawings and pointed out in claims, itsobject being to provide simple, economical and eflicient machines forrapid washing of filter pulp.

Figure 1 of the drawings represents a for the most part verticallongitudinal section view of a washing machine in accordance with myinvention, certain of the parts being in elevation; Fig. 2, a plan viewof a fragment of the machine partly in horizontal section, as indicatedby lines 22 in Fig. 1, a strainer constituting part of the machine beingremoved, and Fig. 3, a transverse section view of said machine.

Referring by numerals to the drawings, 4 indicates a dished bottomhorizontally elliptical tank having an outer lower band 5 to which legs6 are attached. The bottom of the tank is provided with a water inletpipe 7, and a drain-pipe 8 connects with the lower central portion ofsaid bottom. The outlet end of the drain-pipe is provided with a nozzle9 controlled by a gate 10 hung in connection with a bail 11 that ispivotally attached to said nozzle.

Fast on the tank-bottom are socket-bearings 12 in which a pair ofvertical shafts 13 are stepped, and these shafts extend through sleeves14 for which an angular frame 15, supported on the tank, is providedwith bearings 16, said frame being riveted or otherwise rigidlyconnected to an upper horizontal flange 17 of said tank.

Set on a gasket 18 upon a horizontal flange 19 within the tank is astrainer 20 and leading from an upper channel 21 of said tank are pipes22 for overflow water. The strainer comprises a frame of any suitableconstruction and wire gauze in connection with the frame. 7 a I Securedto the shafts 13, below the sleeves 14, and to the sleeves themselves,are blades 23 parallel in series, and these blades eX- tend in oppositedirections from said shafts and sleeves to therewith constitute stirrersfor the material to be treated in the tank.

Fastened by set-screws 24, or other suitable means to the upper ends ofthe shafts and sleeves are bevel-gear wheels 25 and 26 that mesh withbevel-gear pinions 27 fast 011 spindles 28 for which the frame 15 isprovided with bearings 29. Bevel-gear wheels 30 fast on the spindles aremeshed with a bevel-gear pinion 31 fast on a driveshaft 32 for whichbearings 33 are provided on the frame 15, and the drive-shaft is provided with fast and loose belt-pulleys 3st, 35.

Each of the blades 23 is herein shown as being preferably a suitablybent flat metal strip of any preferred width, the contour of said bladein side elevation being approximately that of a rhomboid, and thegearing above specified is such that the blade-carrying shafts andsleeves rotate in opposite di rections. The length, shape anddisposition of the blades is such that the series of same in connectionwith the shafts pass one another twice in one revolution of said shaftsalternately with a similar passing of the series in connection with thesleeves, the stirring and cutting action of the shaftblades being in adirection opposite that of the sleeve-blades to divide the strain andsecure the best results. v

The filter pulp to be cleaned is placed in the tank 4, Water letonthrough the pipe 7 and the mass agitated and cut by the stirrers, theblades of which stirrers cut the pulp until it is thoroughlydisintegrated. The strainer 20 prevents loss of pulp with the overflowwater that finds its outlet through the pipes 22, and the disintegratedand cleaned pulp is run off with water from time to time through thedrain-pipe 8 to be thereafter separated from said water, whereby it isagain in condition for use as a filter.

I claim:

1. A filter-pulp washer comprising a horizontally elliptical tankprovided with a suitably controlled drain-pipe, a pair of verticalshafts for which bearings are provided on the bottom of the tank, aframe mounted on said tank, depending sleeves for which the frame isprovided with bearings and through which sleeves the shafts extend,blades connected in series to the shafts and sleeves to extend therefromin opposite directions, and gearing by which said shafts and sleeves arerotated in opposite directions; the length and disposition of the bladesbeing such that the series of same in connection with shafts pass oneanother twice in each revolution thereof alternately with a similarpassing of the series in connection with sleeves.

2. A filter-pulp washer comprising a horizontally elliptical tankprovided with a screened overflow-water outlet and a suitably controlleddrain-pipe, a pair of vertical shafts for which bearings are provided onthe bottom of the tank, a frame mounted on said tank, depending sleevesfor which the frame is provided with bearings and through which sleevesthe shafts extend, blades connected in series to the shafts and sleevesto extend therefrom in opposite directions, and gearing by which saidshafts and sleeves are rotated in opposite directions,the length anddisposition of the blades being such that the series of same inconnection with shafts pass one another twice in each revolution thereofalternately with a similar passing of the series in connection withsleeves.
